# How to File a Workers Comp Claim in Colorado: Full Guide
H1: How to File a Workers’ Comp Claim in Colorado, Step by Step
The Short Answer
To file a workers’ comp claim in Colorado, first report your injury to your employer in writing within 10 days under C.R.S. § 8-43-102, then let your employer file the Employer’s First Report of Injury with their insurer. If your employer denies the injury, has no insurance, or refuses to report, you file Form WC-15 (Worker’s Claim for Compensation) directly with the Colorado Division of workers’ compensation within the 2-year deadline set by C.R.S. § 8-43-203(1)(d)(I). This process applies statewide, including all claims arising in Colorado Springs and El Paso County.
Most injured workers in Colorado never have to file a single state form themselves. That surprises people. When you learn how to file a workers comp claim in Colorado, the first thing to understand is that the claim usually starts automatically the moment you report your injury to your employer. Your employer’s insurer does the paperwork. The state assigns a claim number. Benefits begin.
But that’s the ideal path. The other path — the one where you have to take control — happens when your employer disputes your injury, has no coverage, or simply won’t file. Knowing which path you’re on is the whole ballgame. And it’s exactly what Alex Kerr helps injured workers figure out every week, whether they were hurt on a job site in Fountain, a warehouse in Cimarron Hills, or behind the wheel on I-25 near Monument.
The Two Paths a Colorado Workers’ Comp Claim Can Take
There are only two ways a claim gets started: the employer-initiated path or the worker-initiated path. Under C.R.S. § 8-43-103, your employer has a legal duty to report your injury to their insurer and the Division. You don’t file anything. The worker-initiated path — filing Form WC-15 yourself — only becomes necessary when that employer duty breaks down.
Think of it this way: reporting is your job. Filing is usually theirs. The confusion starts when workers assume they must file the WC-15 immediately, when in reality the employer’s report has already put coverage in motion. Or the opposite — they assume a verbal “hey, I hurt my back” to a supervisor counts as filing. It doesn’t. While most claims do proceed without formal conflict, disputed claims are common enough that knowing which path you’re on matters from day one.
Step 1: Report Your Injury to Your Employer in Writing
Report your work injury to your employer in writing within 10 days of the incident under C.R.S. § 8-43-102(1) — this is the prerequisite to everything else. Verbal notice isn’t enough. Late notice won’t automatically kill your claim, but it can reduce your benefits, so don’t wait.
We tell every client the same thing: put it in writing, date it, and keep a copy. An email works. A signed incident report works. A text to your supervisor works in a pinch. For the full breakdown of deadlines and what counts as proper notice, see our guidance on how long you have to report a work injury. This step protects everything that follows.
Step 2: Your Employer Files the First Report of Injury
After you report, your employer must notify their workers’ comp insurer and file the Employer’s First Report of Injury (Form WC1) within about 10 days when your injury involves lost time or more than first-aid treatment, per C.R.S. § 8-43-103. During this window, you should be getting medical treatment from an authorized provider and keeping records of every visit.
What should you expect? A call or letter from the insurer’s adjuster. A claim number. Instructions on where to treat. If you hear nothing after a couple of weeks — that’s a warning sign your employer may not have filed. That silence is often the first clue that you’ve been shifted onto the second path.
Step 3: When You Must File the WC-15 Yourself in Colorado Springs
You must file Form WC-15 (Worker’s Claim for Compensation) yourself when your employer denies the injury is work-related, has no workers’ comp insurance, or refuses to report it — and you have up to 2 years from the date of injury to do so under C.R.S. § 8-43-203(1)(d)(I). The statute provides for a 2-year window to file a claim; consult with an attorney if you have an occupational disease or other circumstances that may affect the deadline for your case.
The WC-15 is your formal assertion of a right to benefits with the state. Get the form from the Colorado Division of Workers’ Compensation. Complete it fully — your information, the employer’s information, the date and description of the injury, and the body parts affected. Submit the completed form to the Division at 633 17th St., Suite 400, Denver, CO 80202-3626. Confirm the current filing method — mail, in-person, or electronic submission — by contacting the Division directly or consulting with an attorney, as procedures may vary.
Here’s where honesty matters. Not every worker needs to file this form. That’s why Alex Kerr personally reviews each situation and tells clients plainly whether the WC-15 is necessary or whether the employer’s report already has coverage running. Filing a redundant form wastes time; failing to file a necessary one can cost you the claim. Whether you were hurt in Woodland Park, Security-Widefield, or a job outside Pueblo, the same statewide rules apply — there are no separate El Paso County workers’ comp statutes.
Step 4: What Happens After You File
Once your claim is on file, the insurer generally has 20 days to admit or deny it, and the Division assigns a claim number that follows your case through resolution. If the claim is admitted, wage and medical benefits should begin within weeks. If it’s denied, that 20-day decision starts the clock on your next move. Colorado law, under C.R.S. § 8-43-304, gives the DOWC director authority to assess per-day monetary penalties against insurers for unreasonable delay or denial — current Colorado practice materials indicate those penalties can reach up to $1,000 per day in some benefit-related contexts, which reflects the seriousness with which the state treats an insurer’s failure to timely act on your claim.
Your best asset during this stage is documentation. Keep treating with authorized providers. Save every bill, every work-restriction note, every mileage record. In our experience handling workers’ comp cases across the region, the claims that resolve cleanly are the ones with continuous, well-documented medical treatment. Gaps in care give insurers room to argue your injury wasn’t serious — or wasn’t work-related at all.

Common Filing Mistakes We See
The most common filing mistakes involve confusing verbal reporting with formal filing and missing the reporting window entirely before the claim ever gets to the state. Both can undercut an otherwise valid claim within the statutory limits.
Watch for these:
- Assuming a verbal report equals a filed claim. It doesn’t. Written notice to the employer, then a formal report or WC-15, is what counts.
- Filing the WC-15 with incomplete medical documentation. The Division and insurer need proof of the work connection.
- Not keeping copies. Copy everything you submit.
- Confusing the two forms. The Employer’s First Report is your employer’s job; the WC-15 is yours only when their process fails.
When Filing Triggers the Need for Legal Help
Filing triggers the need for legal help when your claim is denied, when the insurer disputes a pre-existing condition, when your employer retaliates against you, or when processing drags well past the 20-day decision deadline. These are the scenarios where the no-fault system stops feeling simple.
A denial is a common outcome of filing — not the end of the road, but the start of a formal dispute where deadlines tighten. If you receive an adverse order from an administrative law judge, you typically have just 20 days to file a Petition to Review. Pre-existing condition fights, employer retaliation, and delayed processing all share one trait: the insurer is now working against your interest, and the informal cooperation is over. Bradford Pelton PC steps in at exactly these moments, and because Alex Kerr handles every workers’ comp file personally, you’re never handed off to a rotating cast of paralegals. Colorado law provides for penalties against insurers who engage in unreasonable delay or denial, which can include one day’s compensation for each day of violation up to a maximum of 365 days, or up to $1,000 per day depending on the type of violation and the findings of the director or an Administrative Law Judge under C.R.S. § 8-43-304 and related provisions.

Frequently Asked Questions
How long do you have to file a workman’s comp claim in Colorado?
You have 2 years from the date of injury to file a workers’ compensation claim (Form WC-15) in Colorado under C.R.S. § 8-43-203(1)(d)(I). Certain circumstances — such as occupational diseases or good cause for delay — may affect the deadline that applies to your situation. Consult an attorney to confirm the window for your case. Note this is separate from the 10-day deadline to report the injury to your employer.
What are the three main requirements to obtain workers’ compensation?
To qualify for workers’ compensation in Colorado, your injury must arise out of your employment, occur in the course of your employment, and be causally related to your work. Colorado is a no-fault system, so you generally don’t need to prove anyone was negligent — benefits are payable regardless of fault, with narrow exceptions like intoxication or willful self-injury. All three connections to your job must be established for the claim to be compensable.
What is the maximum payout for workers’ comp in Colorado?
There is no single flat maximum payout for a Colorado workers’ comp claim, because benefits depend on your injury type, wage level, and degree of permanent disability. Medical treatment for the work injury is generally covered without a dollar cap, while wage-replacement and permanent disability benefits are calculated under statutory formulas tied to your average weekly wage. Because results vary by case, a review of your specific medical and wage records is the only reliable way to estimate value.
Do I need to file the WC-15 myself if I was hurt on a job in Colorado Springs?
No, most injured workers in Colorado Springs never file the WC-15 themselves because the claim starts automatically once the employer reports the injury to their insurer. You only need to file the WC-15 if your employer denies the injury is work-related, has no insurance, or refuses to report it. If you’re unsure which situation applies, a free consultation can confirm whether coverage is already in motion or whether you need to take control.
How long does it take to get workers’ comp benefits after filing in Colorado?
After a claim is filed, the insurer generally has 20 days to admit or deny it, and if admitted, benefits should begin within weeks. Continuous treatment with authorized providers and complete documentation speed this process along. Delays past the 20-day decision window may signal a disputed claim that needs legal attention.
